Pyright is a static type checker for python created by Microsoft and designed for speed and configurability.

Installing

Note

I am the maintainer of the pyright PyPI package which is a wrapper over the official version.

You can install pyright using pip.

pip install pyright

The official version of pyright can be installed from npm, to install globally run the command:

npm install -g pyright

Pyright can be configured from either a pyproject.toml file or a pyrightconfig.json file, see the official documentation for more options.

pyproject.toml

[tool.pyright]
typeCheckingMode = "strict"

pyrightconfig.json

{
    "typeCheckingMode": "strict"
}

After using any of the installation methods listed above, pyright should now be in your PATH and you can execute as shown:
